Embodiment Construction

[0010] The embodiment of the present invention: the processed elliptical cam such as figure 1 As shown, the shape is an ellipse, the major axis L1=37.54, the tolerance requirement is upper deviation +0.008, the lower deviation -0.008; the minor axis L2=36.46, the tolerance requirement is upper deviation +0.005, and the lower deviation -0.008. The method is as follows:

[0011] First, make a relief grinding elliptical cam. According to the shape of the processed elliptical cam, the relief grinding elliptical cam is designed such as figure 2 As shown, its shape is also elliptical, the major axis L3=51.96, the tolerance requirement is upper deviation +0.005, the lower deviation -0.005; the minor axis L4=50.88, the tolerance requirement is upper deviation +0.005, and the lower deviation -0.005;. Made of wear-resistant materials, it is not deformed, wear-resistant, and has a long service life.

[0012] Secondly, install the finished elliptical cam on the camshaft of the hob shovel gri...

Abstract

A technology for machining the elliptical cam on hobbing-relieving-grinding machine-tool by copying method includes such steps as making a copying elliptical cam, installing it onto the mainshaft of said machine-tool, regulating the machine-tool for synchronous rotation between mainshaft and copying elliptical cam, clamping the blank of the elliptical cam to be machined onto said machine-tool, and turning on the machine-tool to machine said blank until it become a finished product.

Description

Technical field: [0001] The invention relates to a mechanical processing method, in particular to a processing method of an elliptical cam. Background technique: [0002] Harmonic transmission uses the controllable elastic deformation of the flexible element to transmit motion and power, while the controllable elastic deformation of the flexible element is realized by the action of an elliptical cam. Therefore, the elliptical cam plays a very important role in harmonic transmission. At the same time, the higher the accuracy of the harmonic drive, the higher the requirements for the manufacturing accuracy of the elliptical cam. At present, the processing methods of elliptical cams include: (1) turning on a general-purpose lathe; (2) milling on a general-purpose milling machine; (3) machining on a cam grinder. With the rapid development of harmonic reducers, the accuracy requirements for harmonic reducers are getting higher and higher. When lathes and milling machines are used for ...
